I was GUILTY of not educating myself earlier in life…..having been on thyroid replacement medication for decades (and chemically induced menopause in my 30’s for endometriosis) precipitated bone loss later in life even though I was very active and lifted weights; having said that I was also not aware that the body needs other minerals in order to absorb calcium-D3 & K. In addition woman frequently need testosterone following menopause to combat bone loss! visit an endocrinologist, or homeopathic doctor, to get in depth labs and a full evaluation of your body.
